26 that will appear in the data file, with a list of attribute/value pairs.
67 \func{void}{AddAttributeValue}{\param{const wxString\&}{ attribute}, \param{float }{value}}
69 Adds an attribute and floating point value pair to the clause.
71 \func{void}{AddAttributeValue}{\param{const wxString\&}{ attribute}, \param{long }{value}}
73 Adds an attribute and long integer value pair to the clause.
75 \func{void}{AddAttributeValue}{\param{const wxString\&}{ attribute}, \param{wxList* }{value}}
77 Adds an attribute and list value pair to the clause, converting the list into
81 \func{void}{AddAttributeValue}{\param{const wxString\&}{ attribute}, \param{wxExpr* }{value}}
83 Adds an attribute and wxExpr value pair to the clause. Do not delete\rtfsp
88 \func{void}{AddAttributeValueString}{\param{const wxString\&}{ attribute}, \param{const wxString\&}{ value}}
90 Adds an attribute and string value pair to the clause.
94 \func{void}{AddAttributeValueStringList}{\param{const wxString\&}{ attribute}, \param{wxList* }{value}}
96 Adds an attribute and string list value pair to the clause.
105 \func{void}{AddAttributeValueWord}{\param{const wxString\&}{ attribute}, \param{const wxString\&}{ value}}
107 Adds an attribute and word value pair to the clause.
131 These functions are the easiest way to retrieve attribute values, by
132 passing a pointer to variable. If the attribute is present, the
136 functions; no code is necessary to check whether the attribute is

161 \constfunc{void}{GetAttributeValueStringList}{\param{const wxString\&}{attribute}, \param{wxList* }{value}}
164 attribute value retrieval. This function expects to receive a pointer to
166 to the list if the attribute is present in the clause.
172 Use this on clauses ONLY. Searches the clause for an attribute
183 \func{void}{DeleteAttributeValue}{\param{const wxString\&}{ attribute}}
185 Use this on clauses only. Deletes the attribute and its value (if any) from the
241 Normally, you would use attribute-value pairs to add and retrieve data
243 you may need to store attribute values as lists, and pick them apart
379 \func{}{wxExprDatabase}{\param{wxExprType}{ type}, \param{const wxString\&}{attribute},
383 a named attribute (often an integer identification).
398 the functor and a user-specified attribute will be hashed upon, giving the
422 Find a clause based on the special ``id'' attribute.
424 \func{wxExpr* }{FindClause}{\param{const wxString\&}{ attribute}, \param{const wxString\&}{ value}}
426 Find a clause which has the given attribute set to the given string or word value.
428 \func{wxExpr*}{FindClause}{\param{const wxString\&}{ attribute}, \param{long}{ value}}
430 Find a clause which has the given attribute set to the given integer value.
432 \func{wxExpr*}{FindClause}{\param{const wxString\&}{ attribute}, \param{float}{ value}}
434 Find a clause which has the given attribute set to the given floating point value.
452 Finds the clause with the given functor and with the attribute specified
